Multifunctional smoke alarm

Abstract

The invention discloses a multifunctional smoke alarm. The alarm comprises an upper shell, a lower shell and a functional circuit board. The upper shell and the lower shell are connected through internal and external screw threads to form an alarm shell. The four corners of the functional circuit board are provided with installation through holes. A stud installation hole is arranged in the uppershell or the lower shell. A copper stud is used to fix the functional circuit board to the upper shell or the lower shell. The functional circuit board comprises a main control plate, a module I circuit board, a module II circuit board and a module III circuit board. The module I circuit board, the module II circuit board and the module III circuit board are connected to the main control plate, and a connection mode is connector connection or wire rod welding connection. The smoke alarm is based on an original smoke alarm research and development production technology and a production requirement, functions are expanded by adding multiple circuit boards so that product development and launch processes can be effectively accelerated, multiple functions are guaranteed, and the matching of production and a market demand is realized.

Description

technical field [0001] The invention relates to a smoke alarm with extended functions based on the original smoke alarm, in particular to a multifunctional smoke alarm. Background technique [0002] Smoke detectors, also called smoke detectors or smoke detectors, are used to prevent fires by detecting the concentration of smoke. They are widely used in important fire prevention places such as homes, factories, office buildings, hospitals, schools, and museums. The shell and the main control board generally include a smoke sensor, a main control chip, an alarm device and a circuit. [0003] At present, the main control board models of general-purpose indoor smoke alarms are mostly the same, so the functions of smoke alarms are relatively single. However, with the diverse development of the construction industry and the public's multiple requirements for safety hazards and multi-functional products, combined with market demand and technology Development, the demand for increa...

Problems solved by technology

[0004] In order to overcome the defects in the prior art that expanding the function of the smoke alarm puts pressure on technology research and development, product inspection and mass production, and cannot meet the needs of trial production, the present invention provides an extended smoke alarm based on the existing general The functional smoke alarm is mainly a solution for improving the function of the existing smoke alarm. This solution is based on the original research and development and production technology and production requirements of the smoke alarm, and adopts the method of adding multiple circuit boards. Function expansion can effectively accelerate product development and launch process
